An HDMI Switch/Splitter 2-Port (Bi-Directional) is a device that allows you to connect multiple HDMI sources or displays to a single HDMI port. The bi-directional feature means that the device can function in two ways, depending on the use case.

Key Features of a Bi-Directional HDMI Switch/Splitter:

1. 2 Ports:

   • Switch Mode: It lets you connect two HDMI sources (e.g., a game console and a Blu-ray player) to a single HDMI input on your TV or display.
   • Splitter Mode: It allows you to connect one HDMI source (e.g., a laptop or media player) to two HDMI displays (e.g., two TVs or monitors).

2. Bi-Directional Operation:

   • The device can switch between inputs and outputs, meaning it can work either way: it can either switch between two devices (source to display) or split one device to two displays.
   • This flexibility is useful for both home entertainment systems and professional setups.

3. HDMI Version Support:

   • Supports HDMI 1.4 or HDMI 2.0, with compatibility for HD and 4K resolutions (depending on the version).
   • Should also support 3D video, audio return channel (ARC), and CEC (Consumer Electronics Control) if using HDMI 1.4 or higher.

4. Resolution and Quality:

   • Can handle resolutions up to 4K @ 30Hz or higher, depending on the model, with some models supporting 4K @ 60Hz.
   • Ensures high-quality video and audio output, usually up to 7.1 surround sound.

5. Plug-and-Play:

   • Most HDMI switches/splitters are plug-and-play, meaning no extra drivers or software are needed. Simply connect the HDMI cables from the source(s) and display(s) to the device.

6. Remote Control (optional):

   • Many bi-directional switches/splitters come with a remote control for easy switching between inputs or outputs without having to manually press buttons on the device.

7. Powered vs. Non-Powered:

   • Some HDMI switches/splitters require an external power adapter, while others are powered directly through the HDMI connection.
